Hello,
I would like to profile a cabal package that contains template haskell
code. However I get the following error:
$ cabal configure --ghc-options="-O2 -prof -auto-all -caf-all"
...
$ cabal build
...
Dynamic linking required, but this is a non-standard build (eg. prof).
You need to build the program twice: once the normal way, and then
in the desired way using -osuf to set the object file suffix.
What's the best way to solve this?
Currently I do a cabal build -v and copy the ghc --make ... command
line. Then I first build the program normally (without -prof) and then
build it with -prof and -osuf p_o like the error messages suggests.
This is annoying however.
Is there a ticket for this bug?
